First, let's find the total number of contestants who are not 31 to 50 years old and are not wearing tennis shoes:
- Under age 12: 2 (High Heels)
- 13 to 30 years old: 7 (Tennis Shoes) + 7 (High Heels) = 14
- 31 to 50 years old: We want to exclude this category, which contains 6 (Tennis Shoes) + 6 (High Heels) = 12 contestants
Therefore, the total number of contestants who are not 31 to 50 years old and are not wearing tennis shoes is 2 + 14 = 16.
Now, the total number of contestants is:
- Under age 12: 4 (Tennis Shoes) + 2 (High Heels) = 6
- 13 to 30 years old: 7 (Tennis Shoes) + 7 (High Heels) = 14
- 31 to 50 years old: 6 (Tennis Shoes) + 6 (High Heels) = 12
The total number of contestants is 6 + 14 + 12 = 32.
The probability that a randomly selected contestant is not 31 to 50 years old and is not wearing tennis shoes is 16/32 = 1/2.
So, the correct answer is 1/2, which can be simplified as 16/32 = 1/2.
